Application filed October 1, 1918. Serial No. 256,411.

To all whom it may concern:

Be it knoWn that we, ROY ALs'raN LIPPIN- GOLIT, acitizen of the UnitedStates of America, residing at 395 Collins street, Melbourne, in theState of Victoria, Commonwealth of Australia, and EDWARD FIELDERBrLLsoN, a subject of the King oflGreat Britain and Ireland, &c.;residing at :3951 Collins street, Melbourne, in the State of Victoria,Com monwealth of Australia, have invented certain new and usefulImprovements in Fasteners for Hinged Structures; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention covers means for adjusting and fixing or fastening hingedstructures uch as casement windows, especially those opening outward andfitted with a screen, shutter or other element through which part of theadjusting device extends to allow the window or the like to be opened orclosed and held where desired without disturbing the screen, shutter, orother element. The said hinged structure is hereinafter called thewindow, for-brevity.

In the drawings herewith Figure 1 is a plan of one form of the casing ofour fastener; Fig. 2 a horizontal section of that casing; Fig. 3 a sideelevation-of a casing and part of its rod and rod fixing means. Fig. 4shows a sectional side elevation of our fastener relatively to a screen,but with part of its rod omitted. Fig. 5 is an end view of the fastenerthe left side of the easing being in section through the middle of thecasing, and the right side in section through the right hand part of thecasing in Fig. 3. The outer end of the rod is shown upwardly extended.Figs. 6 and 7 are on a smaller scale, andshow our fastener in plan viewwith the window in its closed, and in its open, position respectively.

In these drawings A is a window. B a screen, and C indicates any windowsill, stool, or like base to which the base plate of our fastener willbe fixed. 1 is a hinge plate attached to window A, and 2 a hinge pinconnecting plate 1 to the end of a fastener rod, bar, or tubeshown as arod 3- which passes through a casing 4.

The said casing is rotatable relatively to the base plate 5, which isscrewed down or otherwise fixed to the an or the like c.. 5 7

arev screw holes. The rod is provided in some cases with means by whichto (especially' when the Window is closed) prevent undue projection ofthe rod into the room or. soon, as it is found that a longhori-zon tallyprojecting rod has many disadvantages. Thus the rod may be telescopic,but weshow by way of example a hinge -or joint 3 in the rod. There maybe a,plurality ofthese hinges; as a result the rod end may be swung (forexample upward) as at 3 in Fig[ 5.

As one means of making casing 4'rotatable we show the base plate 5flanged inwardly at 5 to provide a keeper rim over an edge 6 of a plateor suitable member 6 which is fixed'as by screws 6 to form the undersideof casing 4. Part of the casing body has a cylindrical outer wall 4occupying a recess or part of a recess B in the screen B to preventdraft and to exclude dust, insects, and so on, as in every positionwhich the rotatable body assumes it will sufiiciently occupy the screenrecess to cause such exclusion. The screen is not necessarily locatedwith its aperture inclosing one side of the casing as shown. Casing 4 isapertured to have any suitable internal guide'and bearing surfaces 7 forthe rod 3. whereby as the window is opened or closed that rod slidesthrough the aperture. The casing is provided with suitable means to fixthe rod so that the window can be held in any desired position.

As an example a finger nut 8 is shown. engaging the shank 9 of agripping member which is movable to fix rod 3 or to release it asrequired.

This gripping member is shown formed as an eye 10 in which rod 3 is aloose fit. The finger nut 8 (or a washer under it) bears on casing 4,and rotation of the nut raises the eye till the latter grips the rodtightly. 4 is aslot in casing 4 to allow of assembling the parts, and 4is a hole for shank 9. If iti's desired to have a fastening with whichpersons cannot so easily tamper, a plain nut can be substituted for thefinger nut, or other means may be used to prevent the rod sliding.

Operating member 3 on sliding or moving through the part of easing 4 itengages rotates that casing, which continuously keeps aperture B closedin obstruction B, contiguone to the hinged structure to which memher 3is pivotally connected.

Having described this invention What we claim Letters Patent for is 1.Controlling means for swinging closures, comprising in combination avswinging closure and its casing, a rod pivoted to the closure andprovided with a notch, a casting pivotally mounted on the casing, saidcasting having a cylindrical body and an extension projecting therefrom,the casting having a rod receiving opening extendingtherethrough and anotch which communicates with the opening, an eye mounted in theextension and provided with a threaded stem, the eye being seated in thenotch in the extension and adapted to engage the notch in the rod andthe threaded stem passing through the extension, and a lock nut engagingthe threaded extension.

2. Controlling means for swinging closures, comprising in combination aswinging closure and its casing, a rod pivoted to the closure andprovided with a notch, a casting having an annular flange and anadjacent annular groove, a fixed annular flange on the casing to engagein the annular groove to provide a pivotal connection for the casting,the casting having a cylindrical body portion and an extension throughwhich the Z rod passes, and means carried-by the eXten-t sion to lockthe rod in adjusted position.

In testimony whereof we aflix our signatures.
